I received the following response from Sensolutions. Remember that they are located in Canada, but I have not yet identified aanother manufacturer in the US.

Our USB adapters also work with USB direct port drivers, which Ross-Tech
uses. This is the preferred method if you need very tight control of your
data stream timing.

The reason why it would be hard to find OBDII to USB has likely to do with
cost (and development time required): Our adapters sell for $60.00 CAD more
than there equivalent RS232 counter part: $199.99 CAD (~ 146.00 USD)

The price difference for USB is only a bit more the cost of a seperate adapter. I think I'll get one.

There is a four port serial card for sale from www.dashmatics.com. It looks like its a PCI card (surfing there now to find out)YUP. And it is windows compliant. It is only 79 USD. If you already have a serial to OBDII cable for serial to your cars interface, this could be your cheapest solution.
